Our son has had 4 laser tx on his hemangioma that also covers his eye lid. They started laser on him when he was 4 months old (we had to wait only because he was on medication to reduce the growth of the Hemangioma and by 4 months old he was almost off the meds and the h. was flat enough to do laser). The doctor put the sheild (he called it a protective contact on the eye). I think the younger they are the easier it is on them. Just my opinion....but the protecting the eye should not be an issue at any age...they have contacts for all sizes.

Also, it might be important that I let you know that our son is always sedated with a mask (anesthsia) to keep him from moving.
